Momentary push button, 1NO, black XB4BA21

Flush-mounted momentary button – a reliable control element

This black momentary button, designed for mounting in 22.5 mm diameter holes, is a solid and functional solution for controlling various devices and machines. Its versatility makes it suitable for both simple installations and demanding industrial conditions. The construction with a metal front ring ensures durability and resistance to mechanical damage.

Construction and application

The XB4BA21 button is characterized by a flat design and a chrome front ring, giving it an aesthetic appearance. Made of high-quality materials, it guarantees long-lasting and trouble-free operation. Screw connection facilitates quick and secure wiring. Its main task is to start or stop electrical circuits using a single normally open contact (1NO). This makes it ideal for applications requiring simple on/off functionality.

Resistance and safety

The button is designed to operate in harsh conditions. The IP66 protection degree provides resistance to dust and water jets under pressure, making it suitable for both indoor and outdoor applications. It also meets the NEMA 13 standard, confirming its resistance to environmental factors. The metal drive and housing translate into high mechanical strength – this is an element that will perform well even in demanding working conditions. Additionally, the use of new safety alloys increases the level of user protection. Common accessories from the XB4/XB5 series (contacts, light modules) allow for reducing costs related to maintaining inventories and flexible adaptation to the needs of a specific installation.
